Kunlun Mountains are one of the longest mountain chains in Asia, extending more than 3,000 kilometres (1,900 mi).
From the Pamirs of Tajikistan, it runs east along the border between Xinjiang and Tibet autonomous regions to the Sino-Tibetan ranges in Qinghai province. It stretches along the southern edge of what is now called the Tarim Basin, the infamous Takla Makan or "sand-buried houses" desert, and the Gobi Desert. A number of important rivers flow from it including the Karakash River ('Black Jade River') and the Yurungkash River ('White Jade River'), which flow through the Khotan Oasis into the Taklamakan Desert.
Altyn-Tagh or Altun Range is one of the chief northern ranges of the Kunlun. Its eastern extension Qilian Shan is another main northern range of the Kunlun. In the south main extension is the Min Shan. Bayan Har Mountains, a southern branch of the Kunlun Mountains, forms the watershed between the catchment basins of China's two longest rivers, the Yangtze River and the Huang He.
The highest mountain of the Kunlun Shan is the Kunlun Goddess (7,167 m) in the Keriya area. The Arka Tagh (Arch Mountain) is in the center of the Kunlun Shan; its highest point is Ulugh Muztagh (6,973 m). Some authorities claim that the Kunlun extends northwest-wards as far as Kongur Tagh (7,649 m) and the famous Muztagh Ata (7,546 m). But these mountains are physically much more closely linked to the Pamir group (ancient Mount Imeon).
The mountain range formed at the northern edges of the Cimmerian Plate during its collision, in the Late Triassic, with Siberia, which resulted in the closing of the Paleo-Tethys Ocean.
The range has very few roads and in its 3,000 km length is crossed by only two. In the west, Highway 219 traverses the range en route from Yecheng, Xinjiang to Lhatse, Tibet. Further east, Highway 109 crosses between Lhasa and Golmud.
